Ati Radeon 5470 mobility overheats often

It's my first post. I have a problem, here it is: I am playing kinda high-resources requiring games, like BF3, Driver San Francisco, NFS World, etc, and my video card (Ati Radeon 5470 mobility) overheats very often. Laptop just shut down, and when i am turning it on, the BIOS message says that laptop got overheat. And what else i did found out that it shut downs when it reaches 93 - 95 degrees Celsium. And here is another clue: my videocards fan does not even spin! It is shown that fan speed is 0 rpms. And usage is 30%...

how to solve this problem? becouse if i play those games above 20 min, my laptop shuts down! Appreciate your help

If my videocard does not have fan, than only two or even 1 fan left: processor fan (if it exists) and/or main fan, which is doing all the work inside there...3 months before i had nothing similar, no thermal shutdowns or something like that...

and I read about the cooling pads. Would it help to avoid overheat? If yes, than what i should check, notice to the cooling pads parameters? For example; fan size, fan number, fan speed, etc...? If it wouldn't help, what else could i do to reduce videocards temp?

EDIT: is there any way to adjust fan speed? Becouse it works only 30%, no matter what you are playing or doing. I just did a stress test

The G72 is a fairly new model is it not? I've had to deal with many of HP's DV series machines running way too hot. The thermal pads they use on the heat sinks deteriorate rapidly. The fix is simple in concept, replace those with metal. I use .025" copper cut to size and a quality thermal paste. The hard part is you have to take it apart to do it. If your under warranty go through HP.

you mean that metal thing just above the keyboard? Yeah, i noticed that too that when i am playing, i am litterally cannot touch it becouse of heat! It's written "ALTEC lansing" on that thing. If i want to change it, what should i do?

I'm looking at the manual from HP, that’s just the speakers and a switch but the battery is just under it. Is that getting hot? Try removing it and just use the AC, still getting hot in that area? Worst case is replace the speakers. If you don't mind slightly used I'll bet you can find them from $10-$15.

That helps ALOT! Ok, the GPU is activly cooled. I don't know if HP used those dammed thermal pads or not but I would get a quailty thermal compound, like Artic Silver, take it apart and clean and reapply. IF it has pads, they are usually blue in color and seem like small sponges, remove them, measure the gap, I use wax and a micrometer, replace with metal. If you'll google you can find the service manual at HP's website. Its not hard to take apart, just pay attention to what goes where. A camera is helpful. I use an egg carton to keep track of screws. DON'T just pull on wires on the connectors! I made a little tool from a small screwdriver, bent the edge over to make a little hook, works wonders!

Not remove, BUT, it is a total take down. The cooling unit will be the last part you CAN remove. You'll be removeing it, cleaning it up, and makeing some measurements and possibily changes, then it all goes back together. Take a moment an DL the manual and read through it. Its really no harder than taking a desktop tower apart, its just the parts you'r dealing with are smaller. Wish I could post pics and I'd show you some of the ones I've done..
